Мощность света на ранней стадии???

Hey AEZAKMI23, you can run the main lamp at 100%, but I'd turn the bars off for now. a seedling this young only wants about 200 to 400 ppfd. If the bars are 50w each and about 2.5 umol/j, those two alone give about 625 ppfd in a 60x60 tent and 350 in an 80x80. Add the main lamp at full power and it's about 1,000 and 560. so this stretch probably isn't from too little light overall. Side bars can also pull a seedling sideways and upward. The main lamp alone at 100% gives about 375 in a 60x60 and 210 in an 80x80, right in range and coming from above. bring the bars back around week 3, when the plant can use 400 to 600. For the stem, give it a gentle breeze, and at transplant bury it up to just under the first leaves.
